MANN, Aa citizen of the United States, residin the county of Cook and have invented a new and of which the ing at Chicago, State of Illinois, useful Improvement in Boxes,

invention relates to improvements in box-board and involving a base, with surrounding wallsextending upwardly therefrom and carrying corner-extensions connected with walls of the box and flaps on the latter overlying such extensions when the box is formed, the whole being so lconcollapsing of the box for storage purposes. Boxes of this type, where the flaps are secured to end-portions of the box, as hitherto constructed have presented the objection of collapslng when in use of the corner-extensions from engagement with the free overlapping ends of the flaps, owing to the manner of holding the flaps 1n place and the construction of the cornerextensions, which necessitated the placing of the fastening means 'for the flaps so far from the ends of the latter as to permit accidental disengagement of `the extensions from these flaps when the box is in use.

A -further objection incident to boxes as hitherto constructed is that of lack of desired bracing of opposed box-walls by the corner-extensions where the proportions of the box are such as to'cause the diagonal folding lines of the extensions to overlap, as in the case of hat-boxes, such boxes necessitating the cutting away of the upper endportions of the inner ends of the cornerextensions to permit the box to be collapsed. Furthermore, in boxes of the type in which it is designed that the end flaps be held at all times in engagement with the end-portions of thebox carrying them, the fastening means employed for this purpose held the flaps in a manner necessitating the flexing or the springing of the flaps in order that the corner-extensions be passed beneath them for holding such extensions in place. This is a disadvantage, in that the free ends of the flaps are caused to `stand away from the inner sides of the box and thus present obstructions to the removal of the contents by the accidental withdrawing in boxes of the collapsible type for overcom- 1ng the objections above pointed out and thereby provide against accidental collapsing of the box, to afford efiicient bracing of walls of the box by the infolded corner-extension, to obviate flexing or springing of the ends of the flaps, and, generally, to so lmprove boxes of the collapsible type that they' may be manufactured more cheaply and with the minimum amount of stock, and be rendered highly satisfactory for use.

Referring to the accompanying drawings Figure 1 is a section taken transversely through a box of the uncut-corner type constructed in accordance with my invention this view showing the base and side walls of the box in section and the inner side of one of the two similar end-portions of the box in elevation, the box in this figure being shown in set-up kcondition for use. Fig. 2 is a broken section taken on the line 2 of Fig. 1 and viewed inthe direction of the arrow. Fig. 3 is a view like that ofFig. 1 showing the end-flap therein illustrated raised sufficiently to permit of the collapsing of the .walls of the box without flexing the ends of the fiaps. Fig. 4 is a broken section taken at the' line 4 on Fig. 3 and viewed in the direction of the arrow. Fig. 5 is a plan view of the end of the box illustrated in the preceding figures, the box being shown in collapsed condition. Fig. 6 is a section taken at the line 6 on Fig. 5 and viewed in the direction of the arrow. Fig. 7 is a broken view of the blank from which the box of the preceding figures is formed. Fig. 8 is a view like that of Fig. 1 of a box of the same general characteristics as the one therein disclosed, excepting that its proportions are such that its corner-extensions reach short of each other and thus do not overlap as in Fig. 1, the integral flap of this construction being broken away between its ends, one end of the flap being shown in the position it assumes when holding the corner-extension in place and the other end thereof being folded outwardly, the better to disclose details of construction. Fig. 9 is a View like that of Fig. 1 of a box of the cut-corner type constructed in accordance with my invention, the end flap thereof being broken between its ends and positioned as described of the flap of the construction illustrated in Fig. S. Fig. 10 is a View of one of the two similar end-portions of the blank from which the box of Fig. 9 is constructed. Fig. 11 is a View like that of Fig. 9 of a box having the ing from the lateral e ge of the extension to characteristics of the box shown in the last referred-to figure,` differing therefrom in slight details owing to a difference inthe proportions of parts. Fig. 12 is a view like that ofFig. 9 of still another embodiment ofv my. invention illustrating amodification ofthe meansl for holding the Hap in place, the latter being shown broken through the center with the left-hand end turned upwardly and the right-hand end thereof in .a position inwhich the corner-extension cooperating therewith is free to be withdrawn. Fig. 13 is a view like that of Fig. 12 showing the Hap in position for holding the vcornerextensions in place. Fig. 14 is a view like that of Fig. 12 of still another embodiment of my invention. Fig. l5 is a-view like that of Flg. 13 of thev box illustrated in Fig. 14. Fig. 16 is a View like Fig. 1 of another embodiment of my invention, the corner-engaging iaps being shown disconnected there-i from and in' raised position.v Fig. 17y is a i view like Fig. 16 ofthe box therein illus- .t1-ated showing the box in erected and secured condition; and Fig. 18, a plan view of the box of Fig. 16 in collapsed condition.

Each of the constructions of box selected for illustrating a different embodiment of my invention involves, generally stated, a rectangularvbase having four walls, or two sets of opposed walls, with corner-portions,

or extensions, formed of inwardly-extending sections, one set of the walls being provided with inwardly-folding iaps adapted to overlap .the corner-extenslons and to be secured in a manner to hold the latter in place by engagement of these extensions with the free ends of the aps.

Referring particularly to Figs. 1 to 7 inclusive, which illustrate a box of what is known as the hat-box type, the blank from which the box is constructed is represented in Fig. 7 and consists of. a rectangular sheet of box-board adapted to be folded along the i,

lines 21 to form the four corner-portions, or l extensions, 25 of the blank, which are hingedly connected with Vthe ends of the f walls 22 and 23 through the medium of those portions of the lines 20 and 21 which extend beyond their intersection with each other as represented in Fig. 7. Each corner-extension 25 contains a Vdiagonal folding line 26, andis slit along an irregular line 2l leading from the outer edge of the blank to the folding line 26, and alon the line 28 extendthe diagonal folding line 26, whereby each Aextensin 25 is formed in to three sections 29,

30 and 31. 0n eachwall 23 is an extension or flap, 32 of a length approximately equa to the length of the wall carrying it, these flaps being foldable inwardly toward the walls 23 along dotted folding lines 33, be-

yond 'which lines the sections 3l extend as represented in Fig. 7. Each flap 32 is preferably formed with a centrally-disposed tongue 34 on its outer edge and with a fold'- l upright position, in which they extend at right-angles to the base 24, the sections 29, 30 and 31 of each corner-extension 25, in

this operation, foldinginwardly along that portion of the diagonal line 26 which extends from its intersection with the line 27 to the -adjacer'it intersection of the lines 20 and 21, and along the extremities of. the lines 2O and 21 to a position in which the sections `29 and 30 lie fiatwise, with their outer faces together, against the walls 23, and the sections 31, carried by the sections 29, extend-parallel' with the walls 23,' as illustrated in Figs. 1 to4 f inclusive.

lap each other at the central portion of the The sections 31 thus folded overbox as represented in the figures last referred to, in which condition they are secured in place in any suitable manner, as

for example by staples 36 passing through y them and the adjacent wall 23. The section 31 which is inV contact with the vwall 23 reaches preferably from the top to the bottom of this wall, whereas, by preference, the other, overlapping, section 31 falls short of the top of thls wall to-form an upwardly extending tongue 37. After the walls have been erected as described, the flaps 32 may be folded inwardly and downwardly to overlie at their free ends the top edge-portions of the sections 29, the tongues 34 of the flaps in this operation being introduced under the tongues 37, the use of tongues 34 on the flaps 32 being preferred as they facilitate the introduction ofthese flaps under the tongues 37 and. operate in conjunction with the latter to prevent disengagement of extends, as illustrated in Figs. 3- and 4,

whereupon the walls 23 are then swung down and outwardly. along the folding lines `21, and the walls 22r are swung downwardly and inwardly along the lines20 to theposi tion illustrated in Fig. 5, the sections 29 in this operation folding downwardly and inwardly upon' the lines 26 and the outer extremitiesof the lines 21 to the overlapping position represented in Fig. 5. In operat- The box is righted from the position illustrated in Fig. 5 to that illustrated in Fig. 1V

by swinging the walls 23 'upwardly and inwardly, and the walls 22 upwardly and outwardly upon the base 24, the sections 29 in this operation turning at their hinged connections with the walls 22 and sections 30 and 31 and folding to the position illustrated in Fig. 1. During the operation of swing'inor the walls as described, the operator buciles the flaps 32 to the position illustrated in Figs. 3 and 4'for moving their endportions out of the path of movement of the upper edges of the sections 29,' whereby the 'latter may be folded into the position illustrated in -Fig. 1 without flexing, or

springing the ends of the Iflaps. Owing to,

the engagement of thetongues A37 with the fiaps` as described, the latter need not be fully withdrawn from engagement with the tongues 37 during the operation of righting the box as described, and thus just as soon .as the box is righted, the flaps 32 may be moved to position for holding the extensions 25.in place, as illustrated in Fig. 1, by merely pressing flatwise against'the flaps to flatten them out. It will be understood from the foregoing description that in the particular box described, the sections 29 are the only portions of the corner-extensions 25 which fold when the box is collapsed,y

and righted from collapsed condition, the sections 30 and 31 being permanently held in place against the walls 23.

The construction illustrated in Fig. 8 is the same as that shown in the preceding figures, excepting that, owing to the proportions of' the'box, the sectlons 31 of the corner-extensions do not overlap, but reach shortof each other as illustrated, and each section .31, which is separately secured to the wall against which it lies, as by staples 38, carries an upwardly extending tongue 39 nwhich lies closely adjacent tothe line 28 along which'the extension is cut, the tongues 39' beingadapted to engage with registering tonguesy 40 on the adjacent flap 32 as describedl of the engagement of the tongues 34 with,- the tongues 37 of the construction illustrated4 in .the preceding figures. The operation of righting and collapsing the box is the same as that described ofthe construction shown in Figs. 1 to 7 inclusive, the

flaps 32, in these operations, moving with.

relation to the walls carrying them as described of the flaps 32 in Figs. 1 to 6 inclusive, without becoming disengaged during these operations from'the tongues 39.

Referring to Figs. 9 and 10, in which my `only of the four similar ones of which are illustrated, are, formed of but two sections 44 and 45,-instead lof three, the sections 45 being severed from the ends of the walls 23 and hingedly connected with the sections 44 j along the lines 26. -To form the box, one of the two similar ends of which are shown in Fig. 9, from the blank of Fig. 10, the walls 22 and 23 are turned upwardly at their hinged connectionsl with the base 24 to a position in which they extend at right-angles to the base, the corner-extensions 43 being turnedinwardly by theoperator upon the extremities of the lines 21 to a position in which they will lie against the inner surfaces of the walls 23, the free ends of the sections 45 being thus carried to a position in which they overlap each other, in which position they are secured to the walls 23 as by staples 46, as represented in Fig. 9, or

otherwise suitably secured. The section 45 at the left-hand side of Fig. 10 overlaps the,

section 45 at the opposite side thereof and is preferably of slightly less height than that fof the wall against which it lies, as represented in Figs. 9 and 10, whereby an upwardly-extending tongue 47 is afforded as described of theconstruction shown in Figs. 1 to 7 inclusive, for engaging with the flap 32, formed on the walls 23 and constructed like the flaps of the last referred-to figures, the flaps 32 cooperating with the tongues 47 as described of the fiaps 32 in the construction illustrated in Figs. 1 to 7 inclusive. The collapsing and righting of the box is effected in the same manner as that describedof tahe construction illustrated in Figs. 1 to 6 lnclusive, the sections 44 swinging at thelines 26 and their hinged connections with the walls 22, and the flaps 32 optongues 47.

In Fig. 11 I have illustrated a box which lthe disengagement of the latter' 'with the is the same as that of Fig. 9,l except that its sections 45 do not overlap each other, and

, .each section 45 which extends in this case from the top to the bottom of the wall against which it lies, is separately secured thereto as by staples 48, each section of the box shown in' Fig. 11 further differing from those of Fig. 9 in that each is provided with an upwardly-extending tongue 49, these tongues engaging with registering tongues 50 on the fia-p.A The operation of erecting and collapsing the box of Fig. 11 is thev same as that described Vof the construction represented in Figs. 9 and 10, the flaps 32 of Fig. 11 moving with relation to the ,walls 23 carrying them as described ofthe flaps inFigs. 9 and 10 without dise-nga-,glngv from the tongues 49.

The construction shown vin Figs. 12 and 13 is illustrative of another form of lembodiment of that feature of my invention which relates to the connection of the flaps 32 at their free edges with the Walls carrying them. The box illustrated in these figures is of the same construction as that shown in Fig. 8, excepting that the tongues 39 of the lines 21 and the lines 26, which latter in this c'ase extend to the upper edges of the extensions as represented in Fig. 12, away from the Walls 23 upon the act of collapsing the box, Without being withdrawn fromthe slots 51 as illustrated of that portion of the flap 32 which is at the righthand' end of Fig. 12, and as described of the flaps of the construction illustrated in Figs. 1 to 7 inclusive.

The construction of box illustrated in Figs. 14 and 15 is the same as that shown in Figs. 12 and 13, excepting in the particular that upwardly-extending tongues 53 are provided on the Walls 23, instead of mere slots, these tongues engaging with the tongues 52 on the iiaps 32. The parts of the box are so constructed, as illustrated, as

' to permit it to be collapsed and erected from collapsed condition Without entirely disen` gaging the flaps 32 from the walls 23 as described of the construction illustrated in erecting the box and then collapsing it, in

which case the manner of lthus manipulating Athe box is as follows:l Referring to the boxV Y shown in Figs-1 to 7 inclusive, the operation ner-extension 25 will be turned inwardly.

along the outer extremities of lines 26 to cause them to lie at their inner faces against the inner faces of the sections 29, with the result of causing the sections 31 to overlap eachother and lie against the walls 23 when the walls 22 are folded against the base 24, as described. lVhen the parts have been fo-lded'as described, the upper ends of the sections 29 may be' secured in 'position against the walls 23 by the staples 36, or any other suitable fastening means, all as clearly illustrated in Fig. 5. After the walls 22 and extension 25 have been folded as described, the tongues 34 of the flaps 32 will be inserted beneath the tongues 37 as illustrated in the last-referred to figure. The box of Fig. 8 may likewise be formed directly into collapsed-box conditionfrom the blank from which it is formed, the tongues 40 being inserted beneath the tongues 39 When the walls 22 and corner-extensions have been folded into collapsed condition, it being understood that in the case of the box shown in Fig. .8, the walls 22 and sections 29 will not overlap each other, but will lie fiatwis'e against the base 24 and the walls 23 when in collapsed condition, in which posi-` tion the sections 29 maybe secured to the walls 23 as by the staples 28, or any other suitable fasteningmeans. The box of Fig. 9 may be formed into collapsed-box condition directly from the blank of Fig. 10, by turning the walls 22 inwardly and downwardly against the base 24 to cause them to overlap each other, the section 45 during this operation being manually turnedy upon the lines 26 to cause their inner faces to lie -against the inner faces of the sections 44 and the outer faces f thel sections 45 `to lie against the walls 23, the sections 45 overlapping each other as explained of the construction illustrated in Fig. When the parts have been folded as described, the staples 48 may be applied for the purpose hereinbefore described. After the operations just described, the flaps may be inf serted under the tongues 49 to cause them to lie flatwise against the v`walls The` boxes of Figs. 12 to 15 may likewise. be. formed directly into collapsed-box condition from the blanks from which' they are constructed by folding the walls 22 and cornerextension as described of the construction villustrated in Fig. 8, whereupon the means for fastening the sections 31 of these box constructions to the walls 23 may be applied. The flaps 32 will be introduced at their tongues 52 into the slots 51 and under the tongues 53, respectively, after the walls 22 cent box-walls 22 and 23. The members 55 and 56 of each pair are .partially severed from each other along lines 57 and 58 and are hinged together along the diagonal lines 59, the latter intersecting the ends of the slits 58. The upper ends of the members 56, when viewed in the position illustrated in Fig. 17, have their inner corners partially cut away as represented at 60 for a purpose.

hereinafter explained. The end-walls 23 of the box are provided with flapsA 61 hinged thereto along folding lines 62, these flaps being preferably cut away at their ends as indicatedy at 63, whereby sections 64 of reduced length terminating at their outer ends in tongues 65, are formed. The sections 56 are preferably secured to the endwalls 23 against which they lie, as by staples y 66, and the flaps 62 which have longitudinally-extending folding lines 67 lie at the ends of their sections 64 beneath the sections 56 as represented. The box is preferably formed by first bending the flaps 61 inwardly and downwardly on the folding lines 62 to Acause them to lie latwise against the walls 23, and the side-walls 22 and cornerextensions 54 folded inwardly and downwardly flatwise against the base 24 of the box and end-walls 23, respectively, to the position illustrated in Fig. 18, and the fasteners 66 then'inserted. Thus folding the blank causes the ends of the flap-sections 64 to lie beneath the corner-sections 56 and the ends 68 of the flaps 61 to overlie the cornersections 56. To erect the box from collapsed condition, the operator swings the walls 22 outwardly and upwardly and the walls 23 upwardly and inwardly, the corner-sections swinging upon their coperating respective corner-sections 56 at their hinged connections therewith, to the position illustrated in Figs. 16 and 17. Simultaneously with the raising of the walls of the box to upright condition, the operator buckles the flaps 61 upwardly along their folding lines 62 and 67 to cause the ends 68 of the flaps to be withdrawn from the path of movement of the sections in swinging to upright position in which they lie fiatwise against the respective sections 56. After the sections 55 have been swung to the position described and the box has become erected, the operator straightens out the flaps 61 in a manner hereinbefore described of theother constructions illustrated, thus causing the ends 68 of the flaps to be carried down to a position in which they overlap the upper edges of the sections 55, as illustrated in Fig. 17, for holding the corner-extensions in place.

"hen it is desired to collapse the box, the

operator will first upwardlybuckle the flaps 61 as just described, to carry the ends 68 of the flaps to a position in which they will be out of the path of movement of the upper edges of the sections 55, whereupon the end walls 23 are swung outwardly and downwardly upon their hinged connections with the base 24, and the walls 22 are swung upwardly and downwardly upon their hinged connections with the base 24, the sections 55 in this operation swinging upon the sections- 56 at their hinged connections therewith to the position illustrated in Fig. 18. As soon as the bx has been collapsed as described, the operator straightens out the flaps 61 so that they lie latwise againstv the walls 23, with their ends 68 overlapping the sections 56. It will be noted that the flaps 61 are manipulated as described to permit the box to be erected and collapsed without disengaging these flaps at their free portions Y from the ends of the box carrying them, and thus the operation of releasing the cori ner-extensions and locking them in place may be quickly and easily accomplished. The sections 56 are cut away as indicated at. 60 to permit the flaps '.61 to be readily buckled and straightened outvby the operator while in engagement with. the sections 56 for permitting of the collapsing and the erecting of the box.

It will be noted that in each of the constructions illustrated in Figs. 1 to 11 inclusive, the corner-extensions of the box contain slits 28 which extend from the upper edges of these extensions, considering them in the position they occupy when the box is set up, to the diagonal folding line 26, the

position of theseslits, which may be varied as desired, determining the width of that section of each corner-extension which folds when the box is collapsed and set up from collapsed condition, namely the sections 29 and 44 of the corner-extensions 25 and 43 respectively; and thus the lines upon which the sections 29 and 44 fold do not reach to the upper edge of the extensions. The advantages of thus slitting the extensions is that of permitting the flaps 32 to be secured in position on the walls carrying them suffi ciently close to the ends of these walls as to prevent the accidental collapsing of the box l'in use by the movable parts of the extenheight, with relation to their length, as

would cause the diagonal folding lines of the extensions if extended to the upper edges of the latter to intersect each other, wlthout necessitating the cutting olf of the upper edge-portions of those portions of the corner-extensions which lie against the walls 23, 4whereby these walls of the box are provided with braces which extend from their upper to Ytheir lower edges at the central portions of the latter and serve to very elfectually brace and stren then the box-Walls against buckling. The eature of slitting the extensions from their upper'edges to their diagonal folding lines, 26 may be incorporated in a box regardless of the manner in which the flaps I32 are held in place; namely, whether Ythey be permanently secured between their ends to the end-portions of the box, 'thus necessitating the springing upwardly of. the spring ends of the flaps when it is desired that the box be collapsed; whether the flaps be secured in accordance with my-present herein described invention; or whether such flaps are secured in place, as by removable fastening means, after each box-righting op-` i eration.

One of the advantages of so constructing the box as to permit of the moving of the flaps 32 and 61 to a position in which their free ends will be carried out of thepath of movement of those sections of the cornerextensions which foldwhen the box is collapsed and righted from collapsed condition, without disengaging entirely from the endportion of the box on which they are supported, is that of avoiding the necessity of iexing4 or springing the free ends of the flaps, and thus when the latter lie in a posi-- tion in which they overlap the corner-extensions, namely when thebox is set up, they engaging flapfor insuring against the accidental withdrawal of theextension from engagement with` these flaps regardlessyof the 'nd of corner-extension employed. The

' feature of the box just referred to affords a still further advantage, where employed in connection with a box the corner-extensions of which are slit from their upper edges of their diagonal folding lines 26 as described, in that the means on the box for engaging with the corner-engaging flaps, whether such y' means be tongues or walls of openings, or

any other means affording slip-j oints for'the' iaps, may be located suiiciently close to the inner edges of the movable sections of the extensions, namely those edges which coincide with the slits 28, as to eifectually prevent accidental withdrawal of the movable sections of the corner-extensions fromv the flaps coperating therewith when the box is in righted condition, and still retain in the box the feature of constant engagement of thelaps with the end-portions ofthe box. It will also be noted that after 'the flaps 32 have been inserted into engagement with the coperating tongues orslits, as the case may be, carried by the adjacent end-portions of the box, the removal ofsuch flapsffrom engagement therewith is unnecessary, and thus the box is rendered automatically operative, theflaps freely sliding upon the end-portions of the box carrying them without disengaging therefrom, ,whereby the only operations required upon the flaps during the collapsing and righting of the box are those of buckling the iaps and pressing them flat respectively. -The lines indicating the positions of the slits 28 are shown double for clearness o'f illustration, though it will be understood that these lines vof severance may be either slits or slots, as desired.

While. I have illustrated and described the feature of slittingthe corner-extensions from their ,upper edges to their diagonal folding lines 26 in connection With the feature of providing for the movement of the corner-engaging flaps with relation to the end-portions of the box carrying them without disengaging therefrom, I do not wish to 'be understood as intending to-limit my invention to'constructions in which both of these features are present, as these features may be separately incorporated in boxes and still be within the spirit of my invention.

It will be understood that the folding lines in the flaps of Figs. 1 to 15 inclusive instead of extending the full length of the flaps, may'extend short thereof, and'in this respect be constructed like the flap of Fig.

16, and likewise the flaps 61 .may be constructed like the iap's of the preceding figures without departing vfrom the spirit of my invention. i
